IMPROVEMENT .lN GAS-PURIFVING HURDLES OR TRAYS.

Specification forming part of Letters Patent No. 152,729, dated July 7,1874 application filed June 10, 1874.

To all whom it may concern:

Be it known that I, GEORGE IV. DAY, of Haverhill, in the county of Essexand State of Massachusetts, have invented a new and useful Improvementin Lime-Supporting Hurdles for Gas-Purifying Boxes; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawing and to the letters of reference marked thereon,which form a part of this specification.

In the accompanying drawing, Figure 1 denotes a top view of alime-supporting device constructed in accordance with my invention. Fig.2 is a bottom view, and Fig. 3 a longitudinal section, of the same.

My invention has reference to that class of devices used ingas-purifying box for supporting the lime employed for eliminating theimpurities of the gas.

The object of my invention is to produce a simple, cheap, effective, anddurable device for such purpose; and consists in the novel constructionand arrangement of the several parts, as hereinafter described andclaimed.

In the said drawing, A A denote two reetangular wooden bars, and B B twocylindrical grooved bars, the same being tenoned or otherwise suitablyconnected together, and constituting the sides and ends of the frame. (Jis a cylindrical bar disposed transversely of the frame and near themiddle thereof. In long hurdles two of such bars may be employed. Eachof the bars B is formed with a series of annular grooves, a a, &c.,around its periphery, such grooves having a width and depth sufficientto receive a series of flexible cylindrical bars or rods, 1) b, &c.,which are made of rattan or other suitable wood, such rods beingembedded therein, so that their upper surfaces shall be flush or aboutso with the outer surfaces of the bars B B. The rods 1) are made offlexible material so that they may be bent and strained around thegrooved bars B B, and fastened 'to the under side thereof by pins orstaples 0 c, &c., as shown in Fig. 2. These rods may, if desirable, befastened to the top of the bar or bars 0, by pins or staples, as shownin Fig.1. These rods I arrange at such distance apartas will prevent thelime from falling through the spaces between them, which, in practice, Imake about equal in width to the diameter of the rods.

Having describel my invention, what I claim is The improved limesupporting device or hurdle, consisting of the rectangular bars A A,grooved bars B B, one or more transverse bars, 0, and the series offlexible rods 1) I), &c., arranged and combined together substantiallyin manner as shown and described.

In testimony that I claim the foregoing as my own invention, I affix mysignature in presence of two witnesses.
